, iFor. disintegrating the cake .Inoulded, in oil presses it has already beenproposed to, provide disintegrating .devices directly combined .with the soil press, I the arrangement being such that thetalre :asit leaves -;the press passes through ,thedisintegrating .means lyingj in front of. the orifice of the press-being. thereby highly. subdividechthat islbroken .up intosmallpieces. It'hasjalso been proposed, to cause the disintegrating apparatus to rotate with respect to the press,

whereby thebreaking up operation is con-1 siderably assisted. I I y 'Arrangements of this kind are not easy to fix, owing to their relatively complicated structure. They are located in front of the outlet orifice of the press and thus increase the height of such presses, which is already considerable, and also increase the length of the stroke. I

The object of the present invention is to provide an oil press combined with a dis; integrating means, in which these disadvantages a're overcome by the disintegrating means which has the form of a grid being inserted at the bottom in the mouth of the press space, but so as to be capable of being raised, so that the opposing plunger, as it is raised before the press is filled, carries the grid-like set of cutters up with it. During the filling operation and during the pressing operation with the main plunger, which is now usually carried outin stages, the plungers descend, the grid following the opposing plunger until the grid-like set of cutters again rests 011 its support at the lower end of the press space. The opposing plunger continues to recede. During the application of pressure by the main piston the cake is forced out of the press, when it must pass through the disintegrating means which is now fixed at the bottom in the same, where it is disintegrated. The disintegrating up paratus may also be rotated The conditions will be particularly favourable, if the upper end of the opposing piston be provided with projections, such that the projections correspond to the spaces between the cutters of :the disintegrating grid and are of the same height as the set of cutters. On the latter being raised a uniform pressing surface is thus provided which is formed by the end faces of the projections onthe pistons together with the set of cutters lying between the same.

cylinderb. At the lower open end of" the cylinder the set .of cuttersydrests on --s'upports a, from which it; is capableof bei ng I lifted. 'Below i the straining cylinder b {is the usual opposing plunger is andqabove' the straining cylinder the Lfillingan'd pressure plunger .2; which are operated in a known manner. a On the end of the plunger is are projections 11 the height and cross-sectional area of which correspondto the spaces between the cutters m on the set of disintegrating cutters cl. On the plunger is entering the straining cylinder b at the commencement of a series of operations, the projections it will first enter the spaces in the disintegrating arrangement d between the cutters m, a fiat face being thus formed. When continuing to move, the plunger is will raise the set of cutters d from the supports a and carry it along with it, until the top position reached, say at the line y, when the filling operation and the motion of the piston z commence. On the plunger in descending the relative position of the set ofcutters d and the plunger is in no way altered until the set of cutters d has reached the position shown in'Figure 1 and has come to rest on the supports a again. The setof cutters will then be arrested and will no longer follow the motion of the plunger is, so that the projections h on the latter will be with drawn from the spaces between the cutters m. When it is desired to have short broken pieces, the set of cutters 03 will preferably This may he elfected by the supports a resting in circumferential slots in the straining cylinder 6. possible to act on one of the projections either by means'of a rack and worm or by means of a lever having a slot or in any suitable manner thereby turning the sup- It is then I porting arrangement a and with it the set I of cutters m, if stop members and recesses be provided for preventing the set of cutters cl and the supports a from turning with respect to one another when in the position shown in Figure l In order that the plunger 7c can move past the supporting members a, it is provided with a number of longitudinal grooves agfor instance three such grooves.

-AS will be seen from the drawing the disintegrating apparatus is contained in the pressing space itself so that it is necessary to provide intermediate structures between the press ng space and the opposing plunger.

W hat I claim is: v e e 1. A disintegrating means for an oilpress having a cylinden, comprising a set of cut ters, means for supporting the said set of cutters at the lower end otthe pressing cyl-' inder so that they are capable of being removed, a" plunger capable otsliding in the cylinder, an opposing plunger also capable ot sliding in the cylinder and otcarrying the set of cutters along with it during its upward movement and of depositing it again on the supporting means, on the opposing plunger being withdrawn troni the cylinder,

whereby the cake is disintegratedon leaving the cylinder, as set forth.

7 2. The combination claimed in claim 1,

and having projections on the face ot the opposing plunger, the cross-section and height. of which are such that, on entezing the pressing cylinder, they slide between the cutters of the disintegrating means and together with the said cutters form a fiat surface,

7 set forth.
